From Jim Lance: "Some months ago I had the good fortune to be included in a Scripps 
Institution of Oceanography expedition to Islas Reviliagigedos — west Mexico's only oceanic 
island chain. This volcanic group, about 1500 km south of San Diego and 600 km west of 
mainland Mexico, consists of four principal islands with one, Benedicto, having blown its 

OPISTHOBMANCH NEMSLETTER Volume 13, Number 6, Page 22 

top about 30 years ago and remaining almost totally barren to this day. 

Our ship, the Alpha Helix, was until recently the flag vessel of the Scripps research fleet 
and was well equipped for investigations at sea. Althought our program was primarily oriented 
toward the collecting of algae and invertebrates for natural products chemistry research, ray 
14 collector /colleagues aboard were very cooperative in extending their activilies to help in a 
survey of the opistnobranch population from these and the more inshore Tres Marias Islands. 
Although we circled the islands from seaward, it was evident from observation, charts and 
enormous surf that intertidal or inshore collecting wouldn't prove feasible. Thus, most of our 
work was confined to offshore snorkel and SCUBA. In all, I was able to record only a rather 
disappointing 21 species consisting of 123 specimens. Still, 5 of those are undescribed and 
one, an elysoid sacoglossan. probably represents a new genus with affinites to both Caribbean 
and Indo-Pacific relatives." - Jim Lance. 

From Bob Burn: "The first two weeks of April, I spent with Fred Wells of the Western 
Australian Museum. Six days were taken up with field work in the Albany area of southern 
Western Australia, where we collected on soft bottoms, among seagrasses and on reef platforms 
with satisfying results. Albany is situated on King George Sound, an area visited and collected 
by Quoy and Gaimard in October 1826. These Frenchmen described several bubble shells from 
that locality — namely Liloa brevis, Akera bicincta, Adamnestia arachis and Bulla australis 
(now B. quoyii Gray). We were fortunate enough to find all except the third species. Tornatina 
apicluata Take also has its type locality in King George Sound, and a number of living 
specimens were found. 

Two range extensions are worth mentioning. Aplysia ^i^antea Sowerby 1869 was found 400 km 
further south and east than normal, and Crimora multidigitalis Burn 1957 was found 2500 km 
further west than previously reported." - Bob Burn. 

From Kikutaro Baba: "In March I visited New Zealand and Sydney for a short time. 
Fortunately I was able to speak with Dr. M.C. Miller of the Auckland University at his residence, 
and Dr. R.W. Rudman of the Australian Museum at his office. 

In May I tried again to study Melibe of Japan rather extensively. Possibly the most common 
form of our Melibe is referable to Melibe pilosa Pease, i860 in its wide sense, as some of the 
previous authors suggested. The types of M. papillosa (de Filippi, 1867) and M. vexillifera 
Bergh, 1880 seemed to be based both on juvenile specimens of M. pilosa Pease, i860 (s.l.). It is 
hoped, however, that the pilosa specimens from Hawaii will be studied in more detail by the 
local workers." - Kikutaro Baba 


The Los Angeles Oceanic Society's Coastal Monitoring Conference, Seasons in the Sea, will 
held Saturday, June 13, 1981, at the Chace Park Community Building, Mindanao Way, Marina Del Rey, 
California. Several papers on marine life and marine features will be given. One paper by 
John Scotesi is entitled: Sea Hare Migration Phenomenon off Palos Verdes. Conference pre- 
registration is $3.00 per person. 

The fourteenth annual meeting of the Western Society of Malacologists will be held from June 
23, 1981, to June 26, 1981, at San Diego State University. Olmeca Hall will be the focal point for 
housing and some of the evening small gatherings. The actual meetings will be in Aztec Center 
Council Chamber. The following opisthobranch papers are scheduled for presentation: 

Thursday 8:45 AM Symposium: Recent Opisthobranch Research. James R. Lance, Scripps 
Institution of Oceanography, Chairman. 

8:50 AM - A new Species of Anisodoris with a discussion of the taxonomy of the subfamily 
Discodorididae. Sandra Millen, Department of Zoology, University of British Columbia.

At 7:00 PM on Wednesday, June 24, there will be a nudibranch slide show in the lobby of 
Olmeca Hall. 

Throughout the meeting there will be a display of opisthobranch photographic prints and a 
display of literature. In addition, my opisthobranch fiche library and computer system will be 
in a room at Olmeca Hall for use and demonstration along with microfiche readers and other

I apologize for the delay in publishing this 
issue of Opisthobranch Newsletter. I have been 
working for several months to complete an index 
for publication in the ON and have decided that it 
should be printed in draft form so that people can 
start using it and, hopefully, send additions and 
corrections. The wait should be worthwhile. 

Thanks to Dave Behrens, J. A. Ortea, Itaru 
Usuki, Terry GosHner, Malcolm Edmunds, William 
Jaeckle, R. Tucker Abbott, Joandomenec Ros, Hans 
Bertsch, Bob Burn, Sandra Millen, and others who 
have recently sent information for the ON. 


The Western Society of Malacologists, Recent 
Opisthobranch Research symposium, chaired by 
James Lance, included the following Opistho- 
branch papers presented on June 25, 1981: 

A new species of Anisodoris with a discussion 
of the taxonomy of the family Discodorididae.

Range Extensions of Several Opisthobranchs 

from Humboldt County, California 


William Jaeckle 

Recent publications (Behrens, 198O; McDonald 
and Nybakken, 19o1 ) have contributed signifi- 
cantly to our knowledge of the biology of 
opisthobranch molluscs from the Northeast 
Pacific. However, because of the paucity of 
published accounts from northern California and 
Oregon, the zoogeographioal information within 
these works is, in several cases, inaccurate. 
Historically, studies of opisthobranch molluscs 
have centered around two geographical regions: 
from Boaega Bay, California to Baja California, 
Mexico, and from nortnwest Washington to 
northwest British Columbia, Canada. The reported 
distributions of the species present in the 
littoral zone reflect the intensity of study in 
these regions. Unfortunately, few data are 
available from the area between these two 
regions. This paper presents new distributional 
data for ten n'udibranch species from Humboldt 
County, California (figure 1).
